How I Built This

Data pipeline: Crash records queried from UDOT’s ArcGIS REST API (layer 13, 2024), paginated at 2,000 records per call. 18,099 Salt Lake County records processed. Coordinates reprojected from UTM Zone 12N (EPSG:26912) to WGS84 via pyproj.
City assignment: UDOT data has no city field. Cities are assigned from crash coordinates using bounding boxes. Crashes outside defined city boundaries are excluded from the dashboard.
Rollup fields: UDOT pre-computes behavioral flags (DUI, SPEED_RELATED, HIT_AND_RUN, etc.) at the crash level. These are used directly. Substance breakdown (alcohol vs. marijuana) requires the People table and is not included in this release.
